Arma III: the next generation of gaming’s most tactical shooter | EDGE

EDGE: "There is no starker indicator of Arma III’s granularity than its stance system. Press and hold Left Ctrl, and WASD will no longer govern your movement, but your posture. You can lean and sidestep, too, peering and peeking out of cover to shoot at a distant enemy before ducking back to safety. To shift from fully upright to lying on your side on the ground requires you to press the S key eight times. Thank heavens there’s a key that sends you immediately prone, and another to stand you back up again."
